SUPERNAIT 3 Integrated Amplifier

SUPERNAIT 3

Major performance upgrades and now with added love for vinyl.

In the six years since the last NAIT integrated amplifiers were released, our research and development team have worked on a range of amplifier improvements. The result is upgraded power amplifier sections for SUPERNAIT 3, delivering greater pace and intimacy to their musical delivery – whether it's driving a pair of loudspeakers or your favourite pair of headphones.

SUPERNAIT 3 has received significant performance upgrades, including a built-in phono stage, making it a perfect partner for turntables, as well as for streamers, CD players, or any other music source people want to enjoy with the signature Naim sound.

It also includes a Class A preamp output stage which doubles as a headphone amplifier and ceramic heatsink technology that minimises capacitive coupling between the chassis and output transistors for optimum sound quality.

Its inputs are each individually decoupled and hand-wired to minimise noise and interference while internal switching employs ultra-low-noise, constant current sources which are derived directly from the electronic design of the flagship NAC 552 preamplifier.

The SUPERNAIT 3 can be upgraded with our external power supplies, power amplifiers and even cabling upgrades to get the best from all sources. 

Features

With our typical obsessive attention to detail – all in service of achieving the most authentic musical performance – the SUPERNAIT 3 benefits from the following features:

  • Class A headphone amplification
  • Alps Blue Velvet volume control
  • Reed relay input selection
  • Ceramic insulators for the power transistors
  • Galvanically isolated microprocessor control section
  • Microphonic-isolating PCB mounts

Step up from the NAIT XS3 to the SUPERNAIT 3 and you benefit from a range of superior features, all designed to deliver even better sound quality:

  • Full 24V DR module built-in: enjoy the purer power and performance improvement of Naim’s Discrete Regulation technology for the entire pre-amp stage.
  • Larger toroidal transformer in the power supply: provides greater power and speed of recovery
  • Additional leaded through-hole components in the signal path: further minimises negative effects of vibration and transient thermal conditions
  • Chassis-mounted input sockets hand-wired to the circuit boards: offers enhanced vibration isolation
  • Full Alps Blue Velvet balance control

Technology & Craft

The upgrades in more detail:

  • Our R&D team has found a way to more than double the speed of the voltage gain stage, which in turn doubles the rate at which the speaker output stage can react.
     
  • The second gain stage transistors have been optimised, so they no longer need to be shielded by a cascode stage transistor. Removing the cascode means less amplifier stabilisation is required: that doubles the slew rate and delivers an uplift in sound quality.
     
  • The phono circuit topology comprises 3 stages: the gain stage, passive equalisation and final gain and active equalisation. This enables excellent noise performance, extended RIAA equalisation beyond the audio band and great overload headroom.
     
  • All RIAA equalisation capacitors and the RIAA resistors are ‘through-hole’ mounted film designs, with low microphonic pickup and excellent transient performance. As phono stages are 1000x more sensitive than other inputs, this greatly benefits the sound quality.
     
  • Input impedance is 47kΩ in parallel with 470pF capacitive loading;  the gain is perfect for 5mV moving magnet cartridges.

The Ear | SUPERNAIT 3 | Editors Choice , Sep 2019
" The Classic series is still very much alive and kicking and the Supernait 3 is living, musical proof...as the beating heart of a music lover’s system, this integrated may just be the last amplifier most of us could ever want or need"
Hi-Fi+ | SUPERNAIT 3 | Review , Aug 2019
“We know that Naim amps boogie: what is more surprising is that they do it so well in integrated amplifier form and deliver robust imaging.”
The Ear | NAIT XS 3 & SUPERNAIT 3 | Review , Jul 2019
The Supernait 3 is clearly more muscular than its predecessor with stronger image depth and better timing, the latter being largely a result of the extra control in the bass.
